### Multiple elements with `"application"` role do not have unique labels

<div id="locLevel"></div>

Each element with an `"application"` role must have a unique label that describes its purpose

</Column>
</Row>
<Row>
<Column colLg={11} colMd={5} colSm={4} className="toolMain">

### Why is this important?

An element with an `"application"` role is a type of WAI-ARIA landmark region. When there are multiple application regions, they must have unique labels, so people who use assistive technologies can quickly identify and navigate to each application region.

<div id="locSnippet"></div>

### What to do

 * For each element with `role="application"`, either set the value of the `aria-labelledby` attribute of each application to the `id` value of any visible text that appropriately and uniquely describes that application's purpose;
 * OR, use the `aria-label` attribute to add an invisible, unique, non-empty label to each element with the `"application"` role.

For example:

<CodeSnippet type="multi" light={true}>&lt;h1 id="weather"&gt;Weather portlet&lt;/h1&gt;
&lt;div role="application" aria-labelledby="weather"&gt;
    ...
&lt;/div&gt;
    
&lt;div role="application" aria-label="Stock ticker portlet"&gt;
    ...
&lt;/div&gt;</CodeSnippet>

</Column>
<Column colLg={5} colMd={3} colSm={4} className="toolLeft">
